I don't agree with what you say on Asian cultures. Are you referring to the far east? They are just good at copieng everything the European nations initially discovered.

The middle east may have been great a few thousand years ago. Well it is really hard to compare them to anyone else at that stage because they say human life started there. So the rest of the earth was empty. All the asians and africans and europeans came to be as we know them from those early folk around the Tygrus and Eufrat rivers who split out in all directions to populate the earth.

So the middle eastern cultures were great at discovering the basics of mathematics and astronomy while most of Europe was really empty wasn't it. And what are the Greeks and Italians today? Not much.

About the African and American people. Well maybe the Europeans stomped out the Red Indians, but they did a lousy job in Africa. Africa looks pretty black to me. The Europeans basically gave up trying to bring civilization to those barbaric people.
